Geez. Props to demonfoo for finding a way around the MSHTML mess. I gave up early (ran Wireshark in the background, to find that clicking "Submit Query" didn't even try to connect to anything, then had a go with IE6 which made it crash).
For pedants like me who cringe at the thought of running crappy IE7 Wine for W&G, you can do the following steps to copy your registration over to your proper Wine install:
Do steps 1-5.
NOTE: For step 5, install WallaceGromit101_Setup.exe to your proper Wine install (i.e. omit the WINEPREFIX=~/.wine_wgga).
5a.) Open up regedit in your proper Wine install.
Export the key HKEY_LOCAL_USER/Software/SecuROM to a file (e.g. securom-source.reg). Close regedit.
5b.) Open up regedit in your crappy Wine install.
Code:
WINEPREFIX=~/.wine_wgga regedit
Import the key from securom-source.reg. Close regedit.
Do step 6. Remember that you installed W&G to your proper wine install, so cd to "~/.wine/drive_c/Program\ Files/Telltale\ Games/Wallace\ and\ Gromits\ Grand\ Adventures/Fright\ of\ the\ Bumblebees" instead.
6a.) Open up regedit in your crappy Wine install.
Code:
WINEPREFIX=~/.wine_wgga regedit
Export the key HKEY_LOCAL_USER/Software/SecuROM to a file (e.g. securom-target.reg).
Export the key HKEY_LOCAL_USER/Software/Telltale\ Games/Launcher to a file (e.g. launcher-target.reg). Close regedit.
6b.) Open up regedit in your proper Wine install.
Import the two files you just exported.
Wahey! You should now be able to run W&G from your proper Wine install, while keeping all the saved license data from your other registered Telltale games.
