custom form registration for Outlook - install of form on client cutting end of string off!

[movalgirl]

hi all,

I have a custom form which has various settings definined in
myForm.cfg
e.g. I have a registry variable MYURL defined in myForm.cfg

registry9 = MYURL =
http://xxxxxxxxx.zzzzzzz.de/cms/tsi-d/de/news/templateId=renderInternalPage/contentId=1404248/id=1336.html

I install the form with IMAPIFormContainer::InstallForm()

On the client machine, when the form is installed the registry entry
is written under
HKU\Classes\Software\CLSID\<classid of my form>\MYURL
and cutoff
http://xxxxxxxxx.zzzzzzz.de/cms/tsi-d/de/news/templateId=rende

Using MFCMAPI I opened the message in the EFORMS_Registry and the
first attachment contains the
registry Key "MYURL" in the full length.

Question:
Is there a max length for the registry keys defined in the form
configuration file?

thanks,
