[Fixed] Unable to open a mounted drive

[arko]

At times I am unable to open a mounted drive in TC. The issue never shows-up for local NTFS volumes, only for physical optical drives and manually mounted ISO images. Rarely, the bug can be reproduced with user-mode filesystems.

What would be the best debug strategy here? I don't see anything immediately obvious in procmon and would rather not spend time in olly.

Does this happen when you run Total Commander with elevated rights (as administrator)?

On Windows Vista and newer, network drives are mapped separately for each user. Some other drives are treated the same way, e.g. when you use SUBST to add a drive pointing to a subdirectory.
Running a program "As admnistrator" is treated like a separate user. To fix it, either run Total Commander as a normal user, or do the following:
1. Run regedit.exe
2. Go to the following key:
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Policies/System
3. Right click in the right panel, and create a new DWORD entry with the name
EnableLinkedConnections
4. Set the value to 1
5. Restart your computer

Microsoft explains it here:

No, I run it as a regular user. Will try to run an instance with elevated privileges when it happens and report back.

No, the error I know about only occurs when running TC with elevated rights, not when running it with normal rights. It must be something else.

The issue "resolved itself". No idea what was going on there.

Updated subject line to indicate this was fixed. Make sure that wincmd.ini contains the following:

Code: Select all

Allowed=abcdefghijklmnopqrstuvwxyz

Allowed=abcdefghijklmnopqrstuvwxyz

By default, the wincmd.ini doesn't contain any Allowed=
So all drives are allowed.
