I'm running windows XP via Parallels Desktop on my MBP Intel Core 2 duo. Tonight I needed to connect to and use some PC-based software I thought I had previously installed in my virtual machine. Apparently I had not cause it didn't showup.

So I inserted the disk and started over. Upon loading Parallels gave me this message:

Unable to connect CD/DVD-ROM 1.

A file or device required for the operation of CD/DVD-ROM 1 does not exist or is used by another process, or you have no permission to access it. The virtual machine will continue running, but the device will be disconnected.

So I did a uninstall and reinstall of my Parallels - the version originally supplied with my MBP in 06. I started over and got the same message??

So I'm thinking it's a Windows problem and I pull out the Windows XP install disk that also came bundled with my MBP. Now I get this message:

"INF file txtsetup.sif is corrupt or missing.Status 512"

and with that I can't reinstall Windows, I'm left with what is on the machine.

My CD/DVD drive works perfectly on the Mac side and I've even opened the CD in question to be sure the .exe file for Windows is there. It is.

Any idea why Parallels won't connect with my CD/DVD in Windows?????

    In a "pure windows" context, the following utility from Microsoft can sometimes get you past that message to do a reinstall from the CD drive

    (Not entirely sure how that's going to work in the case of a Parallels-on-Mac situation, though.)

    Thanks everybody. I finally slved the problem with Parallels tech support (more later). Turns out the problem was of my own making. I recently installed the 3rd superdrive into my MBP (see thread Superdrive won't read CD/DVDs). As it was not the same Matshida that had been in there, the Windows vitual machine didn't recognize it. All that was necessary was to go into Parallels preferences, use Configure to change the CD set up from Mathshida to "default" and all was fine.

    However, I gotta say Parallels tech support - if out of warrant- is the most convoluted, aggravating thing I've ever encountered. I had to go to the website and buy ($19.95) one time phone support. This got me an ID number. Then I had to create an account on line with user name and password and log into my account. there I had to go to a support section, use my ID # to get a 10-digit support code. Then - and only then - could I call and get to a tech - in Singapore apparently where English was definitely a second language (at best)!

    Incredibly frustrating and far more dfficult than need be.
