yes, I read that on the Silverfast site;
SilverFast editions with version numbers before 6.6.1r2 aren't specially adjusted to the Windows 7 operating system. Older versions possibly may not run on a Windows 7 machine or may cause some errors. For example, installation and stability problems may occur.
So I guess my version is below 6.6.1r2. It says on the site that Silverfast 6 is compatible with Windows 7 64-bit.
It also says
It's always recommendable to use the latest SilverFast version available. If you already own a SilverFast the update is free or available for a discounted rate.
So again I guess I will be able to update. Having never been able to use Silverfast, I don't know if it's worth paying out for an update.
On the site they are promoting;
Experience the advantages of SilverFast's 64bit HDRi format, that is available for the first EPSON scanners now, for the following models of the Perfection series as yet:
Is anyone using this with Windows7 (with an Epson v750)? And is it worth the cost of upgrading from Silverfast 6?
