Thanks for the Preloader fix. I have copied all the VB-related dlls that I can detect from my windows system32 directory into the appropriate WINE directory, but didn't overwrite anything that was already there. Is that correct? However, I am still getting the VB error dialog. The software uses MS Access database, which underlies it. The Aquator installation does not require Access to be pre-installed on the machine. I can't find anything that tells me if I need to do anything specific for Access to work, eg install ODBC? Or whether there is anything else needed for VBA to run? (The software allows for VBA customisation)?
