When I start my computer a warning appears saying “update manager an error occurred”. It’s something to do with Installshield but I can’t get rid of it”
You’ll need to remove Installshield with the Remove Programs functions on the computer. To do this, follow our instructions on Adding and Removing software.
In many situations it doesn’t appear in the Add/Remove programs box and you’ll need to go into your drive and uninstall it manually by running unwise.exe from the file C:\WINDOWS\IsUninst.
To do this, click the Vista Start Button and in the search box at the bottom of the menu that appears type in C:\WINDOWS\IsUninst. This will open the folder for the Installshield remover.
Then double click the Unwise.exe program and the removal of Installshield will begin.
With Windows 7 and Vista system you may get the User Access Control messages warning you that this might be unsafe and asking if you want to go ahead with it. The answer is you do and you should click Yes to continue with the uninstall.
When complete, restart your computer and the problem will be gone.
