After a reboot. when I start Thunderbirdportable 91.6 from my pinned spot on the taskbar - I check the properties map to D:\Applications\ThunderbirdPortable - it now looks to setup an email account!
It was working perfectly prior to the reboot.
How can I get my D:\Applications\ThunderbirdPortable\Data\profile loaded and why did this happen?
How did you pin it? If you pinned it with Windows, it's launching in local mode and using APPDATA for the profile. You can only pin using the PA.c Platform. Try launching ThunderbirdPortable.exe directly in Explorer.
Sometimes, the impossible can become possible, if you're awesome!
Thanks!! Phew, I got nervous that it was gone!
I tested it again, I pinned it as it was running and tried restarting and I got the same problem.
Instead, I created a shortcut and dragged this to be pinned and that worked!!
