Red, the only problem i ever had with bf2142  with vista 64 was memory allocation.
Used to get crash to desktop with an error message saying something like.. Error xxxx amount of memory does not seem sane.
If any of you have or are having this problem read below.

- Error on game load "Memory.dll : sanity check : block size 246157300 ( 234.75MB ) doesn't seem sane", or similar Memory sanity check insane error.
There are several steps to try to resolve this apart from checking your RAM isn't dodgy
(a) Try clearing your page file on shutdown by following this M$ article here:

(b) Try resetting your Pagefile. The error can be due to a corruption of the Pagefile, although this should have been cleared by (a), it may be recurring due to fragmentation. Make a note of the original Windows Pagefile size, set it to 0, then reset it back to the original size.
Every so often GrmRprRG runs a little utility called PageDefrag to make sure there's no fragmentation of his PageFile. You can get it from MS at:

(c) Make sure you have the latest motherboard drivers for your SATA drive (used to be a major issue with BF2).
(d) Reinstall Windows and have a clean install of BF2142. Its quicker than extended troubleshooting if the above fixes didn't work.
If you have two harddrives, install Windows afresh onto your spare drive, and then copy the new BF2142 install back onto the other HD with the problem (you could use an external USB drive for copying the game over if you don't want to fiddle with master / slave jumpers on the drives). Also copy the BF2142 folder in My documents.
All should be ok now.
