inCAD 2010 Installation - AutoCAD folder not detected

Problem

I am attempting to install inCAD 2010 for AutoCAD 2009 or newer, but it does not list my AutoCAD folder as an installation option.  It just tells me to contact MicroSurvey Technical Support.  Help!!

Cause

If you are installing inCAD 2010 for AutoCAD 2009 or newer (including Civil, Civil 3D, Map 3D, or Architecture) than your AutoCAD folder(s) should be automatically detected and presented to you as options for installing inCAD 2010 or newer.  This will occur as a sequence of Yes/No dialogs for each supported AutoCAD program folder it can find.  Simply select Yes on the appropriate option. 

MicroSurvey inCAD 2010 / AutoCAD Compatibility Matrix:

Note 1: MicroSurvey inCAD 2010 or 2011 can only be used with 2009, 2010 or 2011 versions of AutoCAD.  inCAD 2012 will only work with AutoCAD 2012. Other unsupported AutoCAD versions (such as AutoCAD Electrical, AutoCAD Mechanical, etc) will not be detected. 

Note 2: MicroSurvey inCAD cannot be used with AutoCAD LT - it does not have any capacity for vertical applications, scripts, etc.  We offer MicroSurvey embeddedCAD as an alternative.

Note 3:

MicroSurvey inCAD 2010 is distributed as two separate installation files - one for AutoCAD 2009 versions and one for AutoCAD 2010 versions.  Please ensure that you have downloaded and are running the appropriate installation package.

Note 4:

If you are installing inCAD 2010 for a supported AutoCAD 2009 or 2010 version (as listed above) and you are using the appropriate inCAD installation package then your AutoCAD folder(s) should be automatically detected and presented to you as options for installing inCAD 2010.  This will occur as a sequence of Yes/No dialogs for each AutoCAD 2009 or AutoCAD 2010 program folder it can find.  If you have a supported AutoCAD version installed but are not prompted with its folder, this suggests that your AutoCAD probably requires a repair installation to replace the missing registry keys.  If you have reinstalled your supported version of AutoCAD and still cannot install inCAD 2010, please contact MicroSurvey technical support for assistance.

Note 5:

If you are using AutoCAD 2010 x64, AutoCAD Map 3D 2010 x64, or AutoCAD Architecture 2010 x64, then only the inCAD "web install" is compatible, the "full install" will not correctly detect your AutoCAD x64 installation.  (This does not affect 32-bit versions of AutoCAD running under Windows x64.)  The two installations are the same except that the full install includes training movies, which you can always watch online here: http://www.microsurvey.com/downloads/movies/incad.htm
