Running on a Windows 2008 server doing an upgrade to 7.5 SP1 the following Install Readiness Checks failed.
OS_W2K12R2 Install Readiness Check failed even though they are on a Windows 2008 server.
IE 11 Install Readiness Check
Hostname Install Readiness Check
CheckSSLSettingFeatureInIIS Install Readiness Check
Log files had the following error:
CDATA[Error while loading String Resources (Culture English) for InstallReadinessCheck CheckSSLSettingFeatureInIIS.
Exception message: ResX file Root element is missing. cannot be parsed.]]
They had a new PL file. However, they had an old language file symantec_v2.en.pl-lang.xml.zip. This file has the information for the messages that should be returned by the Install Readiness Checks. Since the new PL file had new install readiness checks and they had an old language file it could not find the resx information in the file.
Copied the matching symantec_v2.en.pl-lang.xml.zip and symantec_v2.pl.xml.zip l file to the machine and resolved the problem.
