I would like to bring to your attention an issue I am currently experiencing with xtool.

In the past, I compressed several games with it under Windows 7. Probably most used version by me back then was 047 and 053. I test every archive after creation and back then every one of them tested fine.

However about 2 months ago I switched to Windows 8.1 and I find myself facing decompression errors.
Specifically this almost exclusively relate to reflate(I had one zlib giving me error as well but not all). It is 100% reproducible and do not matter which xtool version I use(I keep ones I compressed anything with just in case). Reflate in archive = 100% fail. Any archive. Due to that I excluded disk issue.

Note that ztool with -cm0 work fine under Win8.1, as well as 32bit xtool-crilayla version. Problem is only xtool->reflate(maybe occasional zlib) from what I seen so far. Thankfully majority of my archives are ztool based due to me stubbornly sticking to it for so long but still quite few of new ones I made use xtool already. xtool doesn't have any fancy switches like -cm0, I tried -t1 to no avail.

I am currently trying all archives to make list of broken ones, I also already installed Win7 under Hyper-V late night and will try more on it later but don't know if environment will be 1:1, maybe xtool is having issues due to memory/exception handling of Win8.1.
Also, I did of course already tried Win7 compatibility(all relevant exe files in chain) as well as running as an admin(real one, enforced through group policy).

If anyone have an idea, I will appreciate it.
