[SOLVED] Errors occured during the installation on win 8.1 x64

Hi.
I’ve recently found Manager and tried to install it on my PC running Windows 8.1 x64.
When trying to install Manager, I encountered these errors:
“Called RunScript when not marked in progress”
Then, when I press OK, this shows up:
“Called InstallFinilize when no install in progress”.
I really like to use this software, but I’m not able to install it!
Any help would be appreciated.
MR.
