I work for a software company that sells a graphics package based on .Net framework. We have a licensing system for serial numbers and protection as well. Our system worked on Windows XP thru 7 on both 32 and 64-bit. We also had it working on Win8 so long as the user set our program to run as the admin under the Compatibility tab. After a user updates to 8.1 the licensing system breaks. Even though the user has "activated" their serial numbers they get messages saying their registration is invalid.
So what kind of administrative level changes did MS make in the 8.1 service pack? Our issues are only present on 64-bit systems that came with Win8 and then updated to 8.1. If a PC had 8.1 from the factory it works with our tools. Reinstalling does nothing, so clearly something in the 8.1 update changed the UAC or admin permissions. When I check user PCs WINVER says all of them are v6.3 and build 9600.
Can anyone offer suggestions for things to look for? Our developers are stuck and we really don't know which direction to even look. Any comments would be appreciated! Thanks
