Installation Error FB 4.5 & FC cs 5.5, need help

Tried installing CS5.5 web premium, everything installed ecept Flash Builder 4.5 and Flash Cataclyst cs 5.5. After trying diffret thins kile installing without av, rebooting serveral times, uninstalling Flash player active x and normal ect....

So i decided to check the log files and found this:

::START TIMER:: [Pre payload :{650C9D09-D5BD-4532-8BEE-01DBC1DF5537}]
In PrePayloadInstallProc
hook checkDirs passed str:
X:\Program Files\Adobe
hook checkDirs passed str:
C:\Users\!Tulingen\AppData\Roaming
detected bad character
CHRC_NULL_POINTER_VALUE
Custom action return code: 1
:: END TIMER :: [Pre payload :{650C9D09-D5BD-4532-8BEE-01DBC1DF5537}] took 1.54282 milliseconds (0.00154282 seconds)

and

::START TIMER:: [Pre payload :{D8CCCF4C-C227-427C-B4BE-736657D2AB7E}]
In PrePayloadInstallProc
hook checkDirs passed str:
X:\Program Files\Adobe

the first one is for Flash Builder and the second on is for Flash Cataclyst

Identified by the bit below

----------- Payload: {650C9D09-D5BD-4532-8BEE-01DBC1DF5537} Adobe Flash Builder 4.5 4.5.0.0 -----------
ERROR: DW030: Custom Action for payload {650C9D09-D5BD-4532-8BEE-01DBC1DF5537} Adobe Flash Builder 4.5 4.5.0.0 returned error. Failing this payload.
----------- Payload: {D8CCCF4C-C227-427C-B4BE-736657D2AB7E} Adobe Flash Catalyst CS5.5 1.5.0.0 -----------

So it appears the installer cant handel any special caracters in username eg. the "!" (exclamation mark).

System OS

Win 7 Ultimate 32-bit

That means i have to change accountname, except if annyone got some idea or solution that might work, any help is appreciated.

Beside this shoud be notified to the team that is making the installer if they don't already know this.
