Yes ,I could not run either. upon trying either of them. Both 32 and 64bit. The last version that I could and can still run was 6.6. After getting the files from the torrent, I tried to run the game and the error shows up, but does not show up when I run 6.6. So, its a new one to me as well. Not sure if its some missing files as I only downloaded the Win32 and Win64 only as a note.
Hm. Well...I can't really say for sure why. It could conceivably be an issue if you have Unity installed on the same machine and there's some sort of conflict. Could also be a Visual C++/.Net error. So fully uninstalling Unity (if that's an option) and/or making sure any MS files are updated properly could be solutions. 0.6.6 is a Steam-only version so, it is somewhat unlikely that you have Steam, use Steam and play Steam games, stay on top of Windows updates (I am assuming), AND have MS VC++ or .NET 'framework/Redistributable' component issues. I suppose some part of the unzip process could have caused an issue, but again, hard to tell.
There are some logs that are generated by the game. IDK if you have them cause of how early the game crashed, but here is what I'd need:

] erasmus: House Party Log Locations
Hey all, for troubleshooting purposes I just want to point out where error/output logs for House Party can be located. See below, and please have them ready if you are reporting a crash or any incident of a pop-up error you think might be related to the game. Note that the .DMP file will only be created in certain cases where the Unity Error Handler itself catches the error. This is all so we can help you resolve your issue and make the game better for everyone. Thanks in advance!
Error log (Engine/Unity related failures that may also correspond with related messages in the in-game debug log, accessed by hitting 'F5'): YOUR INSTALL PARTITION:\ or C:\Users\YOURUSERNAMEHERE\AppData\LocalLow\Eek\House Party\Errors.txt
Steam Apps log (program runtime errors and anything the Steam client is capable of catching): YOUR INSTALL PARTITION:\ or C:\Program Files (x86)\Steam\steamapps\common\House Party\HouseParty_Data\output_log.txt
.DMP file (only generated when you get an error that says something like "The game crashed. The crash report folder named 'DATE_ID' placed next to game executable. Send to the developer of the game!"): Will either be located in your Steam install directory as referenced above for the Apps log, near the actual executable for House Party, OR if you ran a standalone build of the game this log will be in the folder you placed that .exe in.
Also please have a screenshot or some form of capture of the in-game Debug Log (press the F5 key when playing) when the problem occurred, if possible.
