I'm running standalone Thunderbird Portable 102.9 on a network drive (CIFS) from my Windows 10Pro machine. Runs fine, but I can't get it to update using the standalone method. It's the only portable app I use regularly so don't have the PortableApp platform installed.
When I download and install the latest version - 102.10.1 in this case but it's been like this since at least 102.* - it installs okay as far as I can tell, but when I go to start it it just hangs. I get the initial splash screen, but then nothing. No activity on the NAS and no TB tasks showing in task manager even after waiting for an hour or more just in case. I have tried this multiple times with reboots of both the PC and of the NAS the drive is mapped to - same result.
However, if I copy my TB installation folder from the NAS to a physical local drive and then install the update, it all works. I can then copy the installation folder back to the NAS and it runs fine from the shared drive.
More background: I have the TB installation running from my "M:" drive which is mapped via a Windows share (CIFS) to my Synology DS215+ . The userid in use has full access (admin) to that mapped drive and I have no other problems accessing data on that drive. I have been running like this for many years, but the problem only started since I moved from version 91 to 102.0 and has happened at every update since.
Can anyone offer any insights or solutions for me?
