That sound the Windows installer error message (see below). Here is one way it happens, but not saying this is what you did.

- you have to uninstall the previous version of the CAT software and then REBOOT the PC before you try to install the new CAT software. The REBOOT is required even though Win7 does not prompt you to do that.

Note some folks on Win8 have reported similar errors even when they follow the process so it's not a guarantee. There could be other ways to get the same generic installer error.

This is an error message thrown by JAVA during an install. Were you installing as an administrator? If not, log into an administrator account and try again. Microsoft suggests procedures/fixes in response to this error message.

The Microsoft Developers Network (MSDN) suggests, "try the following steps:

1. Run command prompt as Administrator NOTE: right click cmd and select 'run as administrator'
2. Change folder by issuing the following command :

For Windows Vista 32-bit: cd C:\windows\System32 NOTE: should work for Win7 as well.
For Windows Vista 64-bit: cd C:\windows\SysWow64
3. Type the following command and hit Enter:

regsvr32 jscript.dll
4. Type the following command and hit Enter:

regsvr32 vbscript.dll
5. Run the installer again. "

The posts on the Microsoft Partner Network suggest the same solution.

I hope this helps.
