In some rare cases, the User Account Control feature in Windows Vista can prevent write access to certain files and folders, which can prevent SDL Trados Studio 2009 from installing properly.
Resolution
Follow these instructions to turn off UAC:
Go to Start > Control Panel > User Accounts.
Select the option Turn User Account Control on or off.
Clear the check box next to the Use User Account Control (UAC) to help protect your computer option.
Click OK to save all changes.
A dialog box is displayed asking you to restart your your computer to apply these changes. Close all open programs and save any work you may have been working on, and then click Restart Now.
Your User Account Control (UAC) is now turned off. Re-install your SDL Trados software to fix any errors from the previous installation. After installation, turn on User Account Control again.
Root Cause
If you are experiencing problems with installation or simply starting the software for the first time then it may be advisable to disable User Account Control for Windows Vista and reinstall SDL Trados. Installation is normally successful without disabling this Windows feature so only follow these steps if nothing else helps to resolve your issue.
