Thanks opoisso893 - In build 1.6.10 I added the 36 --> 34 / 35 --> 34 for SELF and SPRX - For sprx, the program is already using --np-app-type=SPRX --np-license-type=FREE (the --np-klicensee=%KEY% is omited, so it does not override the klicense) Do you have some example where the program used --np-app-type=EXEC instead of --np-app-type=SPRX ? Is still --np-klicensee=%KEY% required when --np-license-type=FREE ? Can I change the original klic to --np-klicensee=72F990788F9CFF745725F08E4C128387 to always use the free klic?
