Ok. Fixed that java issue (by "msiexec /x {32A3A4F4-B792-11D6-A78A-00B0D0150010}"
http://kb.parallels.com/en/112925).
But now I get another error:
"uninstalling Parallels Web Presence Builder...
MSI: Error! Could not access network location sb.
MSI: Error! Could not access network location sb.
Unable to remove product 'sitebuilder' (code '{ED026812-62A5-4ED4-8ECC-3AE05A555
F43}') with error 1603
ERROR: Action sequence 'remove: uninstalling Parallels Web Presence Builder...'
of package 'sitebuilder' has been failed with code 1603
Not all packages were installed.
Please, contact product technical support.
Press ENTER to exit ..."
When I try to remove the SiteBuilder with msiexec (like I did with the jdk) I get "Could not access network location sb."
