I was able to successfully install and boot up a copy of Windows 98 SE in Parallels Desktop 10. Despite finding a few resources online, I cannot access files on my mac via the guest (or vice versa), connect to the internet, or utilize audio. There is no option to install Parallels tools and I've attempted to do it manually via ISOs I've found online but was not successful. I believe I've checked the appropriate settings as far as file sharing and the like (I have copies of XP and 8 which all run fine). I'm mostly interested in the audio so that I can run an old program. Error message I get is ([Pogram] cannot access your sound device. Please consult the documentation which came with your sound device.) Any insights into how I can at least handle the audio issue so I can run the program would be much appreciated. Some have suggested downloading an audio driver, but I cannot test if it works because there is no way for me to access internet to download to the guest and no way to access host file system within the guest.
