That's a consequence of 
"Base-line Windows / C++ compiler upgraded to Visual Studio 2010 [...] 
runtime libraries for Visual Studio 2008 (msvcr90.dll) are no longer 

Short of recompiling your extension against the LO 4 baseline, another 
option might be to tell users of your extension to first download and 
install the old MS runtime libraries on their system (which are 
available from MS, IIUC).
