So now that we can finally borrow licenses from the License Manager, there are methods in arcpy we can invoke to check for product availability and set the license level, but there doesn't seem to be a method to programmatically borrow the product licenses from the license server.  It would be great to see the below functionality added at 10.2 BorrowProduct (arcpy) Summary Borrows a license of the given product from the License Server for the given number of days. Syntax BorrowProduct (product, {days_to_borrow}) Parameter Explanation Data Type product Product code for the product being set. arcview —ArcGIS for Desktop Basic product code arceditor —ArcGIS for Desktop Standard product code arcinfo —ArcGIS for Desktop Advanced product code engine —Engine Runtime product code enginegeodb —Engine Geodatabase Update product code arcserver — Server product code String days_to_borrow   The number of days to borrow the product license for. The default is the maximum number of days established by the license administrator. Integer Code Sample BorrowProduct example Borrows an ArcGIS for Desktop Basic product license using the arcview module. import arcpy # Borrow an 'arcview' license from the License Server for 30 days arcpy.BorrowProduct("arcview", 30)   BorrowExtension (arcpy) Summary Borrows a license of the given extension from the License Server for the given number of days. Syntax BorrowExtension (extension_code, {days_to_borrow}) Parameter Explanation Data Type extension_code Keyword for the extension product that is being borrowed. 3D —3D Analyst Schematics —ArcGIS Schematics ArcScan —ArcScan Business —Business Analyst DataInteroperability —Data Interoperability GeoStats —Geostatistical Analyst JTX — Workflow Manager Network —Network Analyst Aeronautical —Esri Aeronautical Solution Defense —Esri Defense Solution Foundation —Esri Production Mapping Datareviewer —ArcGIS Data Reviewer Nautical —Esri Nautical Solution Nauticalb —Esri Bathymetry Spatial —Spatial Analyst StreetMap —StreetMap Tracking —Tracking String days_to_borrow   The number of days to borrow the extension license for.

I've developed a lot of custom tools in Python Toolboxes for my end users. From time to time, those tools are updated or refined and I end up having to go to each user's system and update the Python Toolbox for them. So to alieviate myself from that requirement, I put a little custom logic into the updateParameters function of the each tool that compares the user's Python toolbox (.pyt file) against the version of the Python toolbox I've published to a shared drive, using the 'filecmp.cmp()' method. If the comparison returns false, then there is a difference between the two files and the the tool raises an error on all tool parameters telling the user that an update is required. So that means I needed an automated update tool for those Python Toolboxes. So within our maintenance toolbox, I wrote a simple logic update tool. The only thing it is supposed to do is go out to the shared drive, grab the .pyt and copy it back to the user's local 'My Toolboxes' folder, overwriting the existing file if neccesary. Problem is, when I put the source code into the the PyScripter Interpeter, it works fine. If I run it in the ArcGIS Python Window, it works fine. When it is run in the toolbox however, it does not copy the 'SourceFile' to the 'Destination' but the copy function always returns without error as if it did. def execute(self, parameters, messages):         # If parameter0 (Update Location Analytics Toolbox) has been checked by the user         if parameters[0].value == True:             ## User has opted to update the Location Analytics Toolbox                         # Aquire the Published Logic File to synchronize with             arcpy.AddMessage("Acquiring Published Location Analytics Source Logic...")             SourceFile = r"\\cof.ds.capitalone.com\root\SDS_SDS6\36051\GIS_Management\Toolboxes\LocationAnalytics\Location Analytics.pyt"                         # Validate that the Destination exists             arcpy.AddMessage("Validating Destination...")             Destination = r"C:\Users\\" + str(User) + "\\AppData\Roaming\ESRI\\" + str(DesktopVersion) + "\\ArcToolbox\My Toolboxes"             if arcpy.Exists(Destination) == True:                                 # Copy the file                 arcpy.AddMessage("Copying " + str(SourceFile) + " to " + str(Destination) + "...")                 shutil.copy2(SourceFile, Destination)             else:                 arcpy.AddError("Could not locate " + str(Destination) + " on local machine.") Note: The 'User' parameter is a string returned from the 'getpass.getuser()' method provided in the 'isLicensed' function of the toolbox and is declared global. The 'DesktopVersion' parameter is a string returned from the 'isLicensed' function of the toolbox, which simply looks at the user's installed program folder to determine which version of ArcGIS is installed and populates the parameter with 'Desktop10.2' for example, if that is the highest version installed. It is also declared global. I've tried using different copy functions as well, including 'shutil.copy()', 'shutil.copy2()' and 'arcpy.Copy_management', of course slightly altering the 'SourceFile' and 'Destination' parameters as each method requires. In every instance, I get the same result. Works fine in the interpreter, works fine in the Python Window, acts as if it succeeded when run as a Python tool but does not actually copy the 'SourceFile' to the 'Destination'. What gives? ...
