I've installed IG2 before, but it was long ago. After switching to Vista, my laptop could no longer run the installers for either the Beta or Delta versions. But now I'm on W7, so I gave it a shot. the installers are opening, but I get errors and the install fails.
I'm confident that I did nothing wrong following steps, but correct me if I'm wrong. In fact, my upload of TNO's Delta on shsforums is the only known source where people can download the Delta, so this is quite embarrassing. Fortunately, the Delta has a DEBUG file. I'll quote the relevant passages:
Installing [IWG2 Patch]
Copying and patching 1 file ...

Stopping installation because of error.

and further down:
ERROR: Failure("resource [AR0001.ARE] not found for 'COPY'")
PLEASE email the file SETUP-IWG2PATCH.DEBUG to
Automatically Skipping [IWG2 Patch] because of error.
Using Language [Chinese]
[Chinese] has 1 top-level TRA files

On a sidenote, if anyone knows how to change the Delta's language to English, it would make it more playable...
