When trying to launch AutoCAD 2010 as a non-admin user or any other new user whose windows profile was created after AutoCad installation you may get the following errors/warnings:

- Unable to load profile file. Some profile information saved in last session may not be restored.
or/and
- Customization file load failed. File not found: acad
or/and
- Font not found: simplex, Specify Font for FONTALT
or/and
- Missing workspace ribbons

As discussed here – http://discussion.autodesk.com/forums/message.jspa?messageID=6224260

I can confirm the following fix (as provided by Greg.Toews) works.

If the user’s registry profile is corrupt for some reason you can also just delete it and then start AutoCAD. AutoCAD will then create a default profile from scratch. (HKCU\Software\Autodesk\AutoCAD\Rnn.n\ACAD-nnnn:nnn)

So far, we’ve found no issues with the service pack and IE8 runs fine.

I’ll provide more feedback as and when if things change.

The above link points to both the X32 (31MB) and X64 (68MB) versions of SP1. Our initial findings internally are that Inventor opens a little quicker and does seem more stable.

We have also received an link via the Autodesk Subscription System to some Productivity Tools only currently available to those on subscription. These are for Part Modelling, Drawing Management and Assembly Design.  Those users on subscription can download the tools now – Unfortunately, those not on subscription will have to wait until the release of Inventor 2010 next year.
