When I Googled for
"The projector file is corrupt" "Windows 8"
I found this sitehttps://cbt.caeoxfordinteractive.com/mod/forum/discuss.php?d=7
It's about a different software than RHEM, but says the error is caused by Microsoft disabling SecuROM in Windows 8.
According to the Gamersgate page for RHEM Trilogy, the download version uses SecuROMhttp://www.gamersgate.com/DD-RHEMT/rhem-trilogy
The How-To Geek site has an article about the SecuROM problem that suggests it's only disc-based games that are affected. However since you're getting the "director player is corrupted" error, you might see if their "fix" for the error works.http://www.howtogeek.com/230773/how-to-p...-8-7-and-vista/
Re-enable the secdrv service on Windows Vista, 7, 8, or 8.1: If you’re not using Windows 10, Microsoft provides instructions for reenabling the secdrv.sys driver they disabled with the recent security updates. To do this, open a Command Prompt window as Administrator. (Open the Start menu, search for “Command Prompt,” right-click the Command Prompt shortcut, and select Run as Administrator.) Run the “sc start secdrv” command to start the service, and run the “sc stop secdrv” command to stop it afterwards. Microsoft provides instructions for enabling it automatically at boot using both commands and the registry, too.
This will make your Windows PC less secure, and it shouldn’t work on Windows 10, where the driver has been completely removed. If you do do this, you should disable the service when you’re done with the affected game to keep your PC more secure.
