[GIS] ArcMap is not opening

arcgis-10.3arcgis-desktoparcmap

Tried renaming and deleting the ESRI folder in C:\Users\Mus\AppData\Roaming, no luck… Using Windows 7 SP1 32 bit system. When I start ArcMap 10.3 it shows the the program is initializing and loading document… but nothing opens. But ArcCatalog is working fine. Any suggestion?

We just had a similar issue with 10.4, where it wouldn't load ArcMap and then crash and give no error or indication of what happened. Event viewer and checking logs didn't show anything suspicious. It had to do with python libraries being updated back in December. You can fix this by editing your registry.

Try some of the solutions listed in Problem: ArcMap crashes during Loading Document launch stage:

ArcMap unexpectedly exits during the "Loading Document..." stage on startup. No error code is displayed.

[GIS] Arcmap 10.3 crashing on launch using either existing MXD or just launching app

No 100% solution, but i did find a trick that seems to improve the crashing on launch.

When I crash on launch over and over I start the task manager and look for two processes: ArcGISCacheMgr.exe and ArcGISConnection.exe, and i force-quit both processes. I believe they are supposed to quit themselves after quitting ArcMap, but I often find they do not, even after waiting for them to quit on their own for several minutes.

Once I have force-quit those two processes and relaunch ArcMap I find it often launches fine and does not crash. Sometimes it still crashes, but often this fix seems to work.

Use full paths in scripts.

As far as python failing on opening the workspace, you may just be encountering a python format issue with the escape character. It is discussed on this nice blog

to illustrate:

>>> str = "C:\folder\file"
>>> str
'C:\x0colder\x0cile' <--Path being passed to arcpy (Bad)

>>> str = "C:\\folder\\file"
>>> str
'C:\\folder\\file'   <-- Good

>>> str = r"C:\folder\file"
>>> str
'C:\\folder\\file'   <-- Also Good
