MgMap.Create causes crash of 64 bit Web Extensions on Windows

[trevorwekel]

On a pre-release build of 64 bit MapGuide on Windows, maps do not display even though the mapagent and web extensions can process requests. The same issue occurs under .Net and PHP. After some debugging, it was found that MgMap.Create causes a fatal application error. See attached test.php. The following message is generated from the script:

Hello World

Session is7fdbd3ee-82b5-11df-8000-000c2939c959_en_7F0000010AFC0AFB0AFA

SiteConnection is open Resource id ok

New Mgmap ok Problem:
The application encountered a problem and could not finish the operation you just requested properly.

Solution:
If it\'s the first time you met this problem, try again or restart the application / session; otherwise, describe the steps to reproduce this problem to the server administrator for suggestions.

My 2c, just to add another data point.

After some debugging, it was determined that IIS was not picking up the MENTOR_DICTIONARY_PATH environment variable without reboot. Since the coordinate system library was not initialized, the call to MgMap.Create would fail.

One fix is to restart IIS after the installation. Jackie also found some information on IIS environment variable overrides which may be applicable. ​http://www.teachout.com/Blog/tabid/165/EntryId/246/Windows-Environment-Variables-Overrides-for-IIS6.aspx

Test patch for updated reboot logic

Fixed with the reintroduction of mandatory rebooting r5033.

Users who don't want to reboot can ignore the prompt and use the IIS env var override technique described here (​http://www.teachout.com/Blog/tabid/165/EntryId/246/Windows-Environment-Variables-Overrides-for-IIS6.aspx)
