I just got a new Win7(64bit) laptop. My last laptop... ahem... was on XP.
So it's been awhile. To celebrate, I decided I'd dust off OP and install it.
I downloaded Pesty's Enhancement Pack 5.1, and followed his instructions in this thread EXCEPT that I did not patch up as a first step. Anyhow, when it came time to install the SFC Mod Chooser, Windows gave me an error for missing "MSCOMCTL.OCX", which nerfed the scripted SFC Mod runnings and just basically screwed it up to high hell, with nothing runnable when I was done.
So I undid everything. Read about the problem and came across this page:

"The only one thing that solved this to me is installing the following:
http://www.ascentive.com/support/new/libraryfiles.exe onto the Syswow64 carpet, not the System32."
So I did that, and REINSTALLED as per Pesty's instructions (this time patching as he directed), and viola! Things run GREAT!
Oh, and as a final step, I DID install the "OP-Sprites-Lyran-Fusion-Fix" as I think it came about AFTER Pesty's enhancement package.
Note a scan of the install folder by MS Security detected a "backdoor trojan" from the DLL Installer: "Win32/Bifrose.OE" which I am taking to be a false positive. But since the DLLs were already installed at that point, I simply quarantined the offensive file. I don't think that'll mess anything up.
