Hello! Many years I was an VirtualBox-User. But a few features are not working correctly. Now I'm testing the Parallels trial-version and I like it and it works good. Primary I use it with Linux, but I wanna also install Windows 98. Of course I saw a few of the forum posts here. But they are unfortunately not working. There are two problems: 1) After installation and reboot I see this error (sie screenshot)*: Beim Initialisieren des Geräts IOS: Winows-Schutzfehler. Starten Sie neu. After a reset the installation continues normally until the following restart. So I think that's not a problem. But then, nearly at the end of the installation, I get every time the same error about explorer.exe and some DLL's (see screenshot). And this is exactly the same error as with VirtualBox. After this error it's over. Okay, Parallels doesn't support Windows 98. But is it really unpossible to install older systems? On VirtualBox okay - it's freeware. But Parallels Desktop is really expensive and I think I do not buy it, if this doesn't work. Thank you for help! * I'm speaking german and use a german version of Windows .
