Problem installing softwares in Windows 7 Enterprise.

I simply advanced to Windows 7 Enterprise (basically was compelled to do the customized update, in of which not one of the documents or applications are retained, since a standard update is not aided in Vista Home Premium to 7 Enterprise. which was unexpected to me, but in anyways. I just lately had to do a system recover to fix some additional issues anyhow, so setting up over again was no mean feat).

In any case, came out with successful set up, all things seems fine, the product key was confirmed and shows up to be fine to proceed. The issue is that when starting the setup .exe files for a number of the applications I have attempted to set up (Adobe Reader, Skype, Symantec Endpoint Protection, WinRAR, etc.), I get an error prompt which states that the process in question has got "encountered a validation error." I don't quite understand what these means, considering that regardless what choice I pick, the note showed up again with a new Assert offset value.

Skype encountered a validation error

Process name: Skype.exe

Module name: unknown

Assert offset: 3067093A.

Ultimately, following sample of these types of warnings, the software installing will inevitably stopped running and shut down.

Skype has stopped working.

Windows is checking for a solution to the problem…

I didn't get these errors on my Google Chrome and VLC Player. The set up for both of these applications went with no any issues, hence I'm considering that I just have some compatibility complications with the other programs I am attempting to set up. And even though that does not feels likely. At any rate, it is already troublesome, and I would like some help figuring out ways to prevent these prompts. Any support I could get in resolving these will be greatly appreciated.
