Adapting proxo 4.5 to the latest OpenSSL DLLs

[herbalist]

It appears to work on a virtual XP. On 98SE, it doesn't find or recognize ssleay32.dll. Using Dependency Walker, I could see the original DLLs using msvcr70.dll, a copy of which is in the Proxomitron folder. The new DLLs want msvcr90.dll, which is installed, obtained from https://slproweb.com/products/Win32OpenSSL.html, which was also copied to the Proxomitron folder.
I've tried copies of msvcr90.dll from both the 98 and XP systems using all the available KernelEx options. DW reports "device not functioning". According to the site, OpenSSL is still compatible with 98, as are the DLLs. Any ideas what I'm overlooking?
