Symptoms
In some cases the hot fix deployment tool is skipping the installation of newer files. Based on this fact, we are requesting that after installing a hot fix, partners/customers review the Dynamics SL installation folders impacted by the hot fix to verify the necessary files were updated.
A listing of new files being installed and the associated dates are found in the file named Bug{bug#][module].rtf file (example: Bug36432PR) that is included in each hot fix bundle. If during this review it is found that files have not been updated, we request that you contact Microsoft support to get a copy of the proper files.
Please follow the standard procedures to open up a Microsoft support case to request the files. This type of support case will be transitioned into a no charge support case.
Please note that this has not been an issue for Web Apps hot fix deployments.
Resolution
The release of Microsoft Dynamics SL 2015 CU2 will resolve this issue. This means that any new hot fixes created after the SL 2015 CU2 release and installed overtop of SL 2015 CU2 will not encounter this issue.
