The call to LOADLIBRARY for the XA resource manager DLL failed (PostgreSQL & SQL Server)

I am attempting to setup a Linked Server from MS SQL Server 2012 to PostgreSQL 9.3 via Linked Servers & ODBC driver from PostgreSQL. Everything works, until a given query invokes MSDTC, at which point I get an error like this on the SQL Server machine, and the query utterly fails: > The XA Transaction Manager attempted to load the XA resource manager > DLL. The call to LOADLIBRARY for the XA resource manager DLL failed: > DLL=C:\Program Files\psqlODBC\0905\bin\pgxalib.dll, HR=%3, File=%2 > Line=%3.%0 The DLL is in fact that location, so the registry seems to be pointing to the right file. The ODBC driver is 64bit and so is my OS. "File=%2" is pointing to something on the d drive, which doesn't make sense to me, since d drive is a DVD. MSDTC is running... what am I missing? I have toggled Linked Server Properties "Enable Promotion of Distributed Transactions for RPC" to both "True" and "False" and this doesn't change the issue and does not produce a different error. Otherwise, scouring the Internet has brought me nothing. Last thing to point out, my query isn't actually doing any updating - it is just pulling data. So I'm not sure why MSDTC get's invoked in the first place...
