How to allow only ONE (GUI) instance of veracrypt.exe?

As I found out I can start mutliple instances of VeraCyrpt.

How can I restrict it to only ONE instance?

So when I doubleclick on veracrypt.exe and an instance is already running in SysTray then this window should be shown instead of a new instance.

Strange, I'm unable to launch two instances of veracrypt, the already running one always pops up.

But its possible (at least under 64bit Win7) as you can from the following snapshot:


Possibly its because of the cmdline parametr /tc ?

Any solution?

Hello Peter,

Can you post the exact command line you are using for VeraCrypt?

I pinned the following shortcut to the TaskBar:

"C:\Program Files\VeraCrypt\VeraCrypt.exe" /tc

I can confirm your results using my Windows 7 Pro 64-bit system when using the /tc switch. I will not receive new VC main GUI windows if I remove the /tc from the command line. I am using VeraCrypt 1.18 Beta 9 version.

Appears to be a bug related to command line usage with the /tc switch.
