I like this. I respect diving into the assembly; even if it’s not the easiest solution, it’s probably the most entertaining.

For those of you looking for a calculator, I can also recommend the open source SpeedCrunch, especially if you don’t use PowerToy Calculator’s graphing features.

@digitallyhere: I’ve found the free version of OllyDbg pleasant to use for making similar tweaks to other binaries.

Cheers!

There is a free version of IDA but it’s more limited. An easier way to go about this would of been to set a break point on any version checking API you can find for windows via the ollydbg console, wait for it to be hit, then follow the stack backwards into the applications code. Much simpler way to find the relevant code than to use a trace.

is there any free software that does that? ida is pay and ollydbg has a free version (how useful not sure).

Congratulations on your interesting hacking. Power Calculator was a useful tool for me. I was also thinking about doing some hacking to make it work with vista…I never though I would have been so difficult, I could not have done it by myself. Thanks a lot for providing an easy way

I’ve been using this calc for years in XP and could never find a suitable win7 replacement… until today. Your hack has made my day!

I also missed the binary link on the first read, and did the hex edit myself.

Thanks
