I just had the same problem, but found a solution. The solution is NOT the one suggested above.
I am running Win7 Home Premium 64-bit. When I attempt to install Theme Manager 4 via Stardock Central app I get an error message indicating "Archive Integrity Check Failed" - corrupt file. I moved the file to another location & had Stardock Central download another copy of the install file to the same result.
However,
when I try to install via the Theme Manager file I download from
https://store.stardock.com/myaccount/products
it installs correctly (I think; it installed & runs but I have not really used it to do anything yet...). Prior to executing the file from the "My Account/Products" page I set it to run as Admin & set Compatibility to "WinVista SP2" but I may have not needed to do that- didn't try it without Admin or Compatibility.
The files were different - The file downloaded from https://store.stardock.com/myaccount/products is not the same as the file downloaded via the Stardock Central app.
In Short:
Theme Manager (Free) 4.00.exe | via Stardock Central app | NOT WORKING
ThemeManager_enhanced_setup.exe | https://store.stardock.com/myaccount/products | WORKING
Good luck; prior to making my Object Desktop & ObjectDock purchase, I really perused the forums checking for reports of problems. I didn't want to spend a lot of money on buggy software. Of all the reports of problem apps, Theme Manager was reported to be the most problematic.
This really should have been caught in software testing prior to releasing to the members.
