Q.: "My Intel driver randomly crashes with error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. I am running Windows 7. What can be done here?"
A.: Uninstall KB2670838 update. This potentially resolves the issue.
Q.: "My Switchable Graphics drivers (UnifL or original) are randomly crashing. What can be done here?"
The driver crashes when not using high-stress applications (when clocks are not running high). It may crash when idle, surfing the internet, or just sitting on the desktop. It may crash completely with everything frozen on the screen (requiring the power button to be manually used to shut down the computer) or it may recover, saying "AMD display driver has stopped working, etc."
Note: These instructions are for Windows 7. The process should be the same or similar for Windows 8, but may vary slightly. This was tested with Radeon 7690M XT and Intel 3000.
Note: AMD Overdrive, found under Leshcat's "UnifL Tools" menu, must be unlocked for this fix to work. To unlock Overdrive, the latest version of MSI Afterburner must also already be installed.
A1.: The minimum idle clocks need to be raised.
1.Open up the CCC.
2.Go to "Presets" and click "Add Preset..."
3.Name it anything that you want, for example "Raised Idle Clocks."
5.Open Control Panel.
6.Navigate to "Appearance and Personalization."
7.Open "Folder Options."
8.Go to the "View" tab and check the bubble for "Show hidden files, folders, and drives."
9.Click "Apply" and "OK."
10.Open up the C drive.
11.Go to users > [username] > AppData > Local > ATI > ACE.
12.Right click "edit" on the XML document titled "Profiles."
13.Copy everything in the document and close it.
14.At the ACE folder, open the profiles folder. You should see your previously named profile here.
15.Right click "edit" on it.
16.Delete everything that is in it and paste what you copied from the "Profiles" XML document.
17.Scroll down to the bottom where you should see some lines that say Want_0, Want_1, etc.
18.Under the CoreClockTarget values (the first one), change the Want_0 value to 30000.
19.Change the Want_1 value to the same as the Want_2 value (this should be whatever your max core clock is).
20.Under the MemoryClockTarget values (the second one), change the Want_0 value to 45000.
21.Change the Want_1 value to the same as the Want_2 value (this should be whatever your max memory clock is).
22.Under the CoreVoltageTarget, change the Want_0 and Want_1 values to the same as the Want_2 value. The Want_1 value may already be the same.
23.Go to "file" and save the document. Close it.
24.Open up the CCC.
25.Navigate to "Presets" and click "Manage Presets..."
26.Select your preset and click "apply" and then "close."
Congratulations! You should have successfully raised your minimum idle clocks. There's one step left - set it to run on startup.
1.Under your programs, there should be a new program (your preset).
2.Open the program folder "AMD Catalyst Control Center" and then the folder "Presets."
3.Right click on your preset and click "copy."
4.Open up the C drive.
5.Go to users > [username] > AppData > Roaming > Microsoft > Windows > Start Menu > Programs > Startup.
6.Paste in your preset.
On boot, your profile will now automatically be applied. "

A2.: If below method is not applicable for you, please refer to UnifL's "Issue Resolver" menu.
Q.: “I've installed UnifL successfully and rebooted. But when Windows starts to load, i get black screen on AMD card. How can I fix it?”
A.: Change videocard to Intel or Connect to external Monitor or connect via Remote Desktop to your system from 2nd device.
Run UBR tool to change FeatureTestControl value to FFFF. Click here to learn more.
With high possibility this will fix AMD black screen on boot up but you won't be able to change brightness on AMD device.
Q.: “Will my old laptop with Intel HD Graphics (Generation 1) receive proper Switchable Driver for Windows 8?”
A.: Currently it is on experimental stage. Old Generation is supported but don't get surprised if you will face numerous problems.
Q.: “I can't install UnifL - stuck on DSE install. I push install, laptop reboots and again UnifL is asking to install itself. What the hell is going on?”
A.: With high probability, your laptop has "Secure Boot" setting enabled in BIOS. Disable it and try installing DSE again.
However, i would advice to get newest signed with private certificate UnifL set and forget about DSE headache.
Q.: “After UnifL installation, i can't switch cards, i am trying to run CCC or use hardware switch but nothing happens. WHT mate?”
A.: This happens from time to time. Remove ONLY CCC via "Program and Features". Install CCC ONLY via usual AMD installer. Reboot.
Q.: “When I installed the drivers the windows 7 updater notified my about two video drivers available for update… Intel and AMD. Should I update it?”
A.: Never update via Windows 7 / Windows 8 updater from now on. It might likely to break UnifL.
Please refer to Preparations page to learn how to forbid it.
Q.: “Hi, i have “AMD Radeon 7690M” card but when i ‘ve installed your driver in device manager i see other name – “AMD Radeon 7000 HD Series”. Whats wrong? Does it slow down my card?”
A.: Nothing is wrong. And no, It does not slowdown or speed up your videocard. Its only a name string.
Brand drivers are setting direct name, while UnifL is using official releases and official release has generic names to cover all range of videocards.
Q.: “There is a cmd window appearing for a second every time on startup. I can see from the startup applications that it has the name AMD AVT. Do you know what that is? Is it ok if I disable it?”
Q.: “I’ve installed everything, everything went smooth, but my CCC does not appear when i try to launch it. It does not give me an error, just does not start. What should i do now?”
"Also, its can show:” Could not load file or assembly ‘CLI.Implementation’ or one of it’s dependencies. the system cannot find the file specified “. What to do?!!!1"
A.: Its rare and unpleasant bug when moving from one one set to another. You can beat it in various ways:
1. Run tool called `SubInACL` from "UnifL Additional Tools".
2. Go to Windows “Program and Features”
3.Launch “Ati uninstaller”. Select ONLY CCC for uninstallation. Uninstall it. Do not reboot.
4. Launch respective UnifL unpacked set. Check ONLY CCC checkbox and install it again.
5. Reboot after this procedure. CCC should be now operational.
For CCC not working issue all u have to do is:
1. Go to control panel, click on .Net framework 4 and click repair (no need to uninstall & reinstall).
(Net framework4 might be included in UnifL, it will reside at "%Unpacked_UnifL%\Apps\DotNet4Client\dotnet40Client", otherwise you might need to search it yourself).
2. Repeat the process for the other versions of .Net framework in the control panel and repair them as well. Reboot when prompted, if not still reboot.
GPlease note: It might happen that DotNet installation might be totally broken. Please use following utility to fully uninstall DotNet and reinstall it again from scratch. Click here to download it.
3. Uninstall CCC by using custom uninstall of catalyst install manager, select only CCC to be uninstalled.
4. Reinstall CCC again by custom install of catalyst install manager,only CCC will be installed.
5. No need to reboot as such, just right click after the installation, CCC should be working as well as switchable graphics option."
Open respective folder where UnifL is unpacked, navigate to "Packages\Apps\CCC2".
Locate folder "Core-Static-Net4", open it and find "ccc-core-static.msi":
Right click on it and find and click "Repair". Follow on-screen procedures.
If you have also "Core-Static-Net" folder, do the same procedures for "ccc-core-static.msi" in that folder.
If that failed, you can try checking your variables if they are set right. More about it: http://guru3d.com - Forum Topic
If everything failed, you can try using ATiMan Uninstaller. Link: http://gamer.lk - AtiMan Forum Topic
Q.: “I cant uninstall CIM( Catalyst Install Manager ) via “Programs and Features”… uninstaller gives me an error 2753 SetACL64.exe.
Also it can show “windows cannot found ATICIMBIN64InstallManagerApp.exe” error."
A.: Navigate to following folder “%Unpacked_UnifL%\Packages\Apps\CIM\” at respective unpacked UnifL set. First install `ATICatalystInstallManager.msi` from ”Win32″ folder, then from “Win64″. That should do.
Q.: "Unable to play certain kinds of video in Windows 8.
-- Netflix app gives this error:
