For various reasons I have both Lotus 123 Release 9 and Microsoft Excel 2003 on my machine.
For quite a number of years now I have been able to convert 123 spreadsheets to Excel without any problems. However, just recently, without knowingly amending anything on my system, I get the following message 'You are attempting to open a file type that is blocked by your registry policy setting '
I have tried without success to discover how I can return the registry policy setting to its status quo, to enable me to continue making the conversions mentioned. Again, your help please.
