aws toolkit breaks visual studio 2013 after install

I installed visual studio 2013 on a 64-bit Windows 7 machine and then installed the AWS toolkit (AWSToolsAndSDKForNet_sdk-2.3.39.0-ps-2.3.39.0-tk-1.9.3.1.msi) directly after. After installing the toolkit, the activity log contains the following errors when I attempt to start visual studio. No other changes were made to the installation. Any ideas?
