 lasinfo --help in the ''OSGeo4W-64 bit-shell'' crashes with:

 {{{
 procedure entry point "?get_error at LASzipper@@QEBAPEBDXZ" couldn't find in
 the DLL "C:\OSGEO$~1\bin\liblas.dll".
 }}}

 starting a dependency walker session in the ''OSGeo4W-64 bit-shell'' shows
 following issues:

 {{{
 Error: At least one required implicit or forwarded dependency was not
 found.
 Error: At least one module has an unresolved import due to a missing
 export function in an implicitly dependent module.
 Warning: At least one delay-load dependency module was not found.
 Warning: At least one module has an unresolved import due to a missing
 export function in a delay-load dependent module.
 }}}

 having a closer look into the dependency walker results, it seems the isse
 seems to be within ''laszip.dll''
