    Hi, I have an MS-DOS guest OS that I created under Parallels 6. It worked fine under Parallels 8 when I ran OS X 10.9 (Mavericks). However, when I upgraded to OS X 10.11 (El Capitan), I am now getting strange errors -- commands that used to work no longer work. For example, the ASSIGN command which worked perfectly fine before is no longer working, I get "bad command or file name." Similar, the MOVE command -- which is BUILT IN -- is giving me the same error, "bad command."

    I tried creating a brand new MS-DOS OS using the instructions here (http://kb.parallels.com/en/122581). That brand new OS gives me the exact same error when trying to use the built-in MOVE command -- "bad command or file name." I tried this under Parallels 11, in case v8 was causing problems, but the same error continues.

    Why is this happening and how can I fix it? I have a DOS program that I absolutely have to run...

    How can a _built_in_ command fail?!

    (Note: the RENAME and COPY commands work fine, but MOVE does not. I absolutely need the ASSIGN command, which is installed as part of the supplemental 6.22 disk, but that installer won't work without the MOVE command, either!)

    Any help is greatly appreciated.

    I should note: this error occurs even if I boot from the MS-DOS install disk! That is, the "move" command won't work even when booted from the clean install disk! (The install disk was downloaded from http://allbootdisks.com/download/iso.html, as in the instructions in the KB article.)

    So, unless the OS on the ISO itself is bad, this has to be a Parallels problem somehow, no? (Especially since I had an OS that worked just fine under Parallels v6, v7, and v8 under OS X Mavericks, and stopped working with the exact same Parallel 8 under OS X El Capitan.)

    Just to start with the basics,
    have you reinstalled parallels tools?
    What are you configuration settings?
    Is the VM isolated from the mac?
    Please post back and i will try my best to help. Thanks
