Under windows VISTA (blizz says supported) cannot launch blizz app with message :
rstrtmgr.dll is missing
Any help welcome
thank you for your message.
Unfortunately the information provided on our website is not up to date and is not correct.
If you take a look at https://blizz.com/en/ (an not in other languages) you will see that Blizz is supported only starting from Windows 7, so Windows Vista is not supported, I am sorry.
I already asked to our Marketing department to change the wrong information on the non English web version in order to avoid such misunderstanding.
