Switch to an older Amyuni version

In case of problems encountered with the latest Amyuni version, you can switch to the previously installed 5.5.2.7 version of the Amyuni software. To do so, proceed with the following steps.

  1. Start KCM Core Administrator.

  2. Click Stop All to interrupt the KCM Core services.

  3. Remove the KCM Document Processors.

  4. Locate the KCM Core program directory at: <deploy root>\KCM\Programs\5.8\ITP Server\Bin.

  5. In the "bin" folder, perform the following:

    • Rename the folder DocToPDF to DocToPDF-6.0.1.1

    • Rename the folder DocToPDF-5.5.2.7 to DocToPDF

  6. In KCM Core Administrator, add the KCM Document Processors and then start the KCM Core services.

From now on, KCM Core uses the 5.5.2.7 version of the Amyuni software again.

Before uninstalling or upgrading KCM Core, you must undo the above changes. To do so, perform the following actions:

  • Stop KCM Core and remove the Document Processors

  • Rename DocToPDF to DocToPDF-5.5.2.7

  • Rename DocToPDF-6.0.1.1 to DocToPDF

Starting KCM Core and adding Document Processors may be postponed until after the upgrade.
