Previous version of JDBC 3.50 could not be installed on Windows 64-bit using 64-bit JRE. Installing JDBC 3.50 gave an error "Directory not writable" for all directories. Same error message was received, even after running all the process as administrator by turning UAC (User Account Control) off. Workaround for this problem was to use 32-bit JRE on Windows 64-bit to install JDBC 3.50.
This problem was solved in IDS 11.50. Now JDBC 3.50 uses newer version of Install Shield, which allows for JDBC 3.50 to be installed on 64-bit Windows using 64-bit JRE. Now, users no longer have to use 32-bit JRE to install JDBC 3.50 on Windows 64-bit. This makes users life easier, since users do not have to set up 32-bit JRE on 64-bit Windows.
