I recently discovered a really strange bug when using
VP8 and
VP9 on the same system. I guess I'll post it here since it seems to fit... please edit my post if it's not supposed to go here.
Name:
VP8 to
VP9 Switch Bug
Symptoms: After opening the
VP8 .exe, the computer system seems to "lock" into a mindset of playing only
VP8 tables when you then try to open
VP9 tables in
VP9.04 or .05. Running the tables in the newer versions of
VP9 gives errors about scripts, such as "unable to open WPC.VBS" or similar, "Can't load VPinmame Variable is undefined", "VPinMAME ver 01560000 required." and etc. (The later errors seem to vary depending on table, these are for emulated
VP9 tables such as Attack from Mars or Lord of the Rings. Original
VP9 tables seem to just get random script errors or crashes if they decide to run.) As a side note, I'm running windows 7 64 bit, and
VP8 and earlier versions of
VP9 need permission from Administrator to run and change the computer no matter what options I've tried to find
Solutions: After some frustrations and uninstalling/reinstalling, I did find a work around fortunately. Recommend you install the
VP Installer on this website (backing up your roms, tables, etc if you need to remove your old installation). It should install not only
VP8 but an early version of
VP9,
VP9.02. This is important. Download the latest version of
VP9 (Currently
VP9.05) and put it in the Visual Pinball folder with the other
VP#.exes.
Now, whenever you play a
VP8 table, and want to play
VP9 but can't because your computer is stuck in that
VP8 mindset... Simply close
VP8, open
VP9.02, then close that. Now, open
VP9.05 and run your table. It should work without a hitch and no script errors.
Reason: Heck if I know, maybe one of you coding-type peoples can look into this and find out what's causing this? I'm not sure what's going on. If you need any more information from me, or can lend more valuable info as to what's going on, please ask or let us know what might be causing this.
Hopefully, this has been helpful!
