set the Windows version to 7 in winecfg.
The only difference seems to be that you used 32 bit prefix. Mine is 64 and didn't have an issue before. The rest (PoL, Mint) should not make a difference.
Anyone else who uses 64 bit prefix and has the issue, or uses 32 and doesn't?
Just did a clean install on a 64-bit prefix using PoL, no overrides, wine-staging 2.21. Had to change Windows version to XP to get the client installed as it would not complete using Windows 7, but once it was installed I could change the Windows version to Windows 7 and was able to install Hearthstone through the client. All web content in the BNet launcher loads successfully and Battle.net Helper.exe did not crash for me. It seems as though this bug is only affecting installs on 32-bit prefixes.
