Alfresco 7.1.1 thumbnail not getting generated (Windows)

Question

We have installed Alfresco 7.1.1 Enterprise version. Alfresco is working fine and we are able to preview documents in Share. However it is not generating the thumbnails for these documents.

When we tried to test the document transformation from the admin console, it shows the following error.

1             pdf  png  TestTransform.pdf 23.1 KB Local:pdfToImageViaPng
1             workspace://SpacesStore/2ead5401-59f6-49ef-8065-03a1bad1ee97

1             Finished in 51 ms

We also has given modify and read & execute permissions to the H:\Alfresco-Transform-Service\alfresco-pdf-renderer\alfresco-pdf-renderer.exe file. We even tried to run the tomcat , start-transform-core-aio.jar and activeMQ as an Admin but still it gives the same error.

We have also installed the GhostScripts, however it is not mentioned anywhere on the Alfresco's website. :-(

Any help will be appreciated.. thanks

It turns out that the server machine needed to be restarted after the Windows upgrade. After restarting the server machine it started working.
