CHM not opening from network folder RRS feed

  • Question

  • Hello,

    I can't find anything answer to my problem:
    One user complained that he could not open CHM file.

    He mentioned, after vacation everything worked.

    What I found:
    .chm not opening from network folder, after copy this file on desktop, problem solved. But the person is working with much .chm document, and copy all uncomfortable. 

    What I tried:

    • Change HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions MaxAllowedZone to 1;2;3;4
    • Create UrlAllowList in regedit.
    • Uninstall last installed windows updates. 
    • Open from another (administrator) user on this pc.
    • Change location of .chm file f:\ g:\ and other mapped disk, or open path with ip: \\\folder\file.chm
    • No "#" or "%" symbol in file name or path.
    • No choose "unblock" in properties.
    • Other computers with same windows from image, can open this file from network folder.

    Maybe you have more ideas? Thanks.

  • Hello,

    I have the exact same problem and tried everything. I worked on a solution for 4 hours now but I finally gave up. I will try if I can get it to work on windows 7 but no chance on windows 10. Can we please have a solution for that.
