Good day to all,
I have the same problem :
I just installed RC4, and got the email with the new keycode, but after I have inserted the Key, the registration window has hanged for a few seconds and then has shut down. Nothing had happened.
I did all the installation as an administrator (RC run on Win 7 - 64).
A few month ago, RC wath installed on a laptop and did work very well after installation. I Have now returned to a desktop (same OS, almost same architecture) and I just can't install RC 4 !
I used RC4 for years on different computers without any problems.
I tried adding all the DLL's like explained under error 713 and 75 without any result.
I have twice asked for new keys (all the same after all) without result.
I have the same problem when I try ti install under both fS9 and FSX, so I don't think the problems come from FS.
I don't see any more what I could do.
Excuse my poor English, thanks for any help,
Pierre
