Hi, I have been trying to install ArcGIS 9.3 on my new PC with Windows 7, but unsuccessful.  The attachment shows the error message shown when I tried to start ArcMap.
So far, I have figured out that I need a new version of License Manager (  I run the installer, but got an error message saying "The file C:\Program Files (x86)\ESRI\License\arcgis9x\ARCGIS_LM.LOG could not be opened.  Access denied."  (The last part may be a bit different, because it was shown in another language in my computer.)  Following this message, another error message appeared indicating that I do not have the admin access, which is not true (i.e., I do have that). 
What should I do now?  Any help will be appreciated.  Thanks!
