Hello,
is it possible to run thunderbird 1.5.02 and portable thunderbird 1.5.02 on a winXP at the same time.
Everytime I start portable thunderbird and thunderbird is already running (and viceversa) it says that thunderbird is already running.

It is, but it can cause issues between the two in the newest version. PTB backs up and then restores TB registry keys and start and exit. There is an INI setting to allow multiple instances which disables the backup... so if you have TB set to check if it's the default, PTB will check on launch, too.
Check the ree in PortableThunderbird\Other\PortableThunderbirdSource for full details and a sample INI file.
Sometimes, the impossible can become possible, if you're awesome!
