I get this error in my Web Site, after installing MSM files.

Question

Background: I've been struggling for 6 weeks to deploy a Web Site with Crystal Reports to a Test Server. After wading thru pages and pages of documentation, some of which had conflicting information, I finally found someone who was able to confirm that I do need to install MSM (merge modules) in order to get my Web Site to work. So I followed the instructions on the MSM package, and installed them on the server, using the defaults that came up. Additional background can be found in my posts in forumID=313, threadID=1285303.
I published my web site to the virtual directory my LAN people set up for me. I went out to a browser, and put in the URL. It actually came up. This is an improvement from earlier tries. I selected the date from the calendar control, and selected the name of the report I wished to display for that date, and get an error (copied, below). Does this error relate to the Merge Modules or to my application? It's kind of vague.
Server Error in '/MicsaReports' Application.

Hi Robert,
This may be permission issue. Domain users need access to "C\Windows\Temp directory"and to the report directory.
suspect permissions is the issue here. To find out what is missing, use Process Monitor:
[http://technet.microsoft.com/en-ca/sysinternals/bb896645.aspx]
Filter on the process, otherwise the log file will be way too huge, then look for "Access Denied" messages.
Please provide us some more details like:
What CR product you are using and its patch level?
The VS that you have used?
Is it with one or with all reports?
Are the reports saved with data?
Regards,
Shweta
