Hi Marek,
Under C:\Program Files (x86)\SAP\SapSetup\setup: or C:\Program Files\SAP\SapSetup\setup, can you search for files, sap*wkstaui.xml, that have ProductVersion is set to 2147483647?
If you have this situation, SAP helped me resolve it with the following.
Delete the files sapaldwkstaui.xml and sapnwbc40wkstaui.xml. Search for files, sap*wkstaui.xml, that have ProductVersion is set to 2147483647. Change the value of this xml attribute to ProductVersion="1" On my test PC I could only find SapBiWkstaUI.xml. If the attribute ProductVersion has a different value than 2147483647 you can leave it alone.
As a rule. If you find a sap*wkstaui.xml (lower case) without an according Sap*Wksta.xml, please delete this sap*wkstaui.xml. If there is a Sap*Wksta.xml without an according Sap*WkstaUI.xml, this is ok.
Extract the two files from SAP Note 1658830 called SapALDSetup.xml and SapALDShared.xml. Unpack the files to the 'Setup' directory of the LiveCycle Designer 9.8 installation. The existing files should be overwritten. When the file, sapaldwkstaui.xml, is deleted SAPSetup will think that ALD is not installed which requires running NwSapSetup.exe.
The erroneous state with ProductVersion="2147483647" only occurs on the hosts installation/update with SAPSetup 9.0.24.0. Other hosts are not affected.
If ALD is installed on such a host, you can set all ProductVersion="2147483647" to ProductVersion="1" and call NwSapSetup /update. This will update all installed products on the host, that are available on the installation source, to the version of the installation source (either an installer or an installation server).
Note: The ALD9.8 media on this DVD has already had the two files updated from SAP Note 1658830.
Cheers,
Dan Mead
