I use the nsis installer to build and support my package. I alsouse ooSQLite in the package and prior to the last release of ooSQLite,I simply copied the needed files to the appropriate folder. That willstill work, but I would like to add detection to my installer suchthat I would only install the ooSQLite modules if there is a laterversion or if it was not originally installed on the target system.For ooRexx and ooDialog, I use the system environment area incombination with a simple rexx command to collect the level ofeach component and then only install them if the ones in the releaseare a later level. Is this, or a similar method available with theooSQLite release? All I would need would be a capability todetect if it is installed via Rexx and if so, return the level ofthe installed package. Thanks for any suggestions.
