When we upgrade agent (6.0.2 to 6.0.3) we have a WIndows error : "1901 Error attempting to read from the source install database: C:\Windows\Installer\xxxxx.msi"
Server is WIndiows Server 2012 and is SCCM Server of PCI Compliant environment.
Have you had similar experiences ?
Some folks have suggested turning off antivirus tools during the install got past the 1901 error. Just google "msi 1901 server 2012 r2" for more details. This isn't a Splunk error, but a windows error.
