The following error is encountered when running the Litespeed installer ....
Error 2203.Database: C:\WINDOWS\Installer\aeb2a875.ipi. Cannot open Database file. System error -2147024629
Generally it is related to the temp environment variable being bad or somewhere the installer can’t use
Adjusting the Temp and Tmp environment variables from their default values can cause this error
WORKAROUND:
How to edit the environment variables back to default:
1. Right-click My Computer --> Properties --> Select the Advanced tab --> Select Environment Variables
2. In the section titled "User Variables for Administrator" edit the TEMP and the TMP values to be the following:
Variable Name: TEMP Variable Value: %USERPROFILE%\Local Settings\Temp
Variable Name: TMP Variable Value: %USERPROFILE%\Local Settings\Temp
