Hiya,
We recently received a case in which the license key was working fine with the fresh install but was giving the errors: 'Setup can not read the existing license key' while upgrading.
If you ever face something similar you might want to check what you get when you run the following query:
select parm_value from custom_sysparams where parm_name=’CRMCRC’
If you get random encoded numbers and strings then try the following after taking necessary backups.
- Run IISRESET /stop command in command prompt.
- Run this statement to nullify the value : Update custom_sysparams set parm_value=null where parm_name=’CRMCRC’
- Do an IISRESET /start command.
- Login to Sage CRM
Hope this helps!
Kind Regards,
Seema Singla
