\uD83E\uDD14 Problem
FIPS (Federal Information Processing Standards) is a security framework, that's usually only mandatory for non-military federal government agencies, contractors, and vendors in the United States.
With FIPS enabled, the CapaInstaller Agent Service cannot always start.
\uD83C\uDF31 Solution 1 - Disable FIPS for the CapaInstaller Agent
Disable FIPS for the CapaInstaller Agent Service by adding the line below to the "C:\Program Files\CapaInstaller\Services\Cistub\cistub.exe.config" file.
The line must be added exactly as shown in the <runtime> section of the file.
<enforceFIPSPolicy enabled=”false”/>
Restart the CapaInstaller Agent Service to activate the changes.
\uD83C\uDF31 Solution 2 - Reconsider using FIPS
As previously mentioned, FIPS is designed for federal government agencies, contractors, and vendors in the United States. Maybe it’s not strictly necessary to enable FIPS in your organization ?
