MID Server will have an error which includes:

C:\Windows\Sysnative\WindowsPowerShell\v1.0\powershell.exe

Example when running upgrade:

Error encountered when invoking PowerShell, the result from running '"C:\Windows\Sysnative\WindowsPowerShell\v1.0\powershell.exe" -noninteractive -nologo -noprofile -command "$ver = if (Test-Path Variable:\PSVersionTable) { $PSVersionTable.PSVersion } else { (get-host).Version }; 'full_version:' + $ver.ToString() + ', major_version:' + $ver.Major"

Example when enabling Credential-less discovery:

"C:\Windows\Sysnative\WindowsPowerShell\v1.0\powershell.exe\" is not recognized as an internal or external command

All currently supported releases

This error is due to a 64-bit host running a 32-bit MID JRE. Sysnative is a virtual Windows folder, a special alias, that can be used to access the 64-bit System32 folder from a 32-bit application or script.

To confirm the version a MID server is using:

1. Navigate to the MID server list
2. Add column "MID Java command directory" to see the location of the JRE being used
3. On the MID server host navigate to the directory where the JRE is
4. Run command "java -version"
5. Example of 64-bit JRE:

   openjdk version "1.8.0_181-sncmid1"
   OpenJDK Runtime Environment (build 1.8.0_181-sncmid1-b13)
   OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)

   Notice above the "64-bit" in the version.

If using OOB JRE

1. Stop the MID server service
2. Move the current MID's JRE folder to another location
3. In the instance go to "MID Server > Downloads" and download the 64-bit MID package
4. Move the new 64-bit JRE folder into the directory specified in "MID Java command directory"
5. Restart the MID server service
6. Go to the MID in the instance and wait for it to come up
7. Click on the error on the MID Server issues tab
8. Change the state to New and choose Update
9. Attempt to reproduce issue in order to confirm resolution
