Ditto, again, a bad suggestion... You may try if it fixes it, but I doubt it and I recommend leaving it on. About the problem, can't help out though because I don't play SH/use JSGME.
There are some things you could check though:
- use a 3rd party (un)zip tool (WinRAR, 7zip) to unpack archives. Unpacking to Program Files is a problem under regular user account, see below.
- verify folder permissions of <SH4>\Data. Make sure you have read/write access.
- install onto non-system drive preferred (both game and JSGME). The game its default install location (<Program Files>) on Vista is protected against writes. Because JSGME is writing/moving files around it will fail if run under a regular user account. Installing the game onto another drive or at least not in <Program Files> should fix this.
- try running JSGME in XP2 compat mode
- try running JSGME with 'admin' permissions
Note that these are individual suggestions. One may work, or some combined. I don't know.
Again:
- In no way should you change/replace folder permissions on system folders. Ever!
- Don't change your entire account to 'Admin', instead use 'Run As Administrator'
- Leave UAC on.
If it still doesn't work, you may try contacting JScones. Maybe he has some hints.
Hope this helps...
