I am using WL4 and WL5. I would like to use both with Taipan Metastock export function , but the dll has a problem.
For WL 4 you need the Metastock Export version 4.6.011 and for WL 5 you need Metastock Export
version 5. So if I unregister Export version5 then WL 5 is not running anymore. I have to register
WL 5 again then it is working, but then in WL4 you can´t open any charts with Metastock format, because you need version 4.6.011
Again unregister WL5 and with regedit load the dll again with the WL 5 verson. WL5 is running again.
Is there any possiblity to read both with one register dll, because this take time and time again.

As repeatedly explained in ticket 20249 last year, then on the forum: ML downloader, this phenomenon is called the infamous "DLL-Hell" problem and the solution is to stick with WL6.

Eugene,

In future versions if you use Isolated COM you might be able to resolve some of these issues.

Thanks for the pointer Dave (I don't work with COM though.)

Here's one good blog post on Isolated COM which mentions manifest files. I wonder if it's possible by modifying the contents of the .manifest file to actually direct an assembly to use a particular version of a COM DLL?
