SYMPTOM:
After setting the 'Path to Strategy Office Installation' link from the Strategy Web Admin page to a path where the officeinstall.htm file is found, users may still receive a 'The page cannot be found' error when accessing the link in Strategy Web 9.0.x.

Sample Code/Error

The error is thrown even though the user has specified a valid url path to the officeinstall.htm file where the Strategy Web Services install is:
Further, clicking the Go button from the Web Administrator page to test the link results in the expected Office installation page:

After clicking 'Save' and attempting to access the link from the Strategy Web Home page, users hit the 'The page cannot be found' message shown above.

CAUSE:
A possible cause for this behavior is the use of the 'Automatically append locale-specific path' option which was added to the Strategy Office Installation page in Strategy 9.0.x.

Using this option, users will notice that the URL specified for defining the Office Installation link changes so that '/Lang_1033/officeinstall.htm' is appended to the given URL.

When this is appended, the URL path specified by the user becomes invalidated.
ACTION:
There are two options for resolving this issue:

Either one of the options above should lead users to the Strategy Office Installation page when the 'Install Strategy Office' link is clicked from the Strategy Web Home page.
