TEST REPORT: Running updated osm models (converted from 1.4.0 to 1.6.0) with OpenStudio 1.6.0 produced the following results: (1) OpenStudio produced an out.idf file, while in the process of the "json" user file script a stderr file was produced with the following messages: DL is deprecated, please use Fiddle QSslSocket: cannot resolve TLSv1_1_client_method QSslSocket: cannot resolve TLSv1_2_client_method QSslSocket: cannot resolve TLSv1_1_server_method QSslSocket: cannot resolve TLSv1_2_server_method QSslSocket: cannot resolve SSL_select_next_proto QSslSocket: cannot resolve SSL_CTX_set_next_proto_select_cb QSslSocket: cannot resolve SSL_get0_next_proto_negotiated

(2) when I tried to start EP simulations with the out.idf file via EP-Launcher, a) the OpenStudio Version of EP 8.2.0 crashed (regularly) b) the stand-alone version of EP 8.2.0 successfully completed the simulations

(3) after de-installing the separate stand-alone version of EP8.2.0, OpenStudio still was unable to run EnergyPlus (!).

 During de-installation(s) of EnergyPlus versions, there is the option of not removing several DLLs,
 because they might still be needed by other programs: I chose not to have these DLLs removed.

(4) Testing execution of the same osm models with the Linux version of OpenStudio 1.6.0 produced better results: these simulations were completed successfully.

CONCLUSION: de-installing the seperate EnergyPlus 8.2.0 (Windows 7) does not help ! The deeper causes remain unclear.

(5) NEXT TESTS:

 de-install OpenStudio 1.6.0;  
 re-install OpenStudio 1.6.0;
 trying to run simulations from osm models fails the same way as described in (1)

 re-install extra EP 8.2.0 on separate drive.
 Now I can at least run simulations again by procedure  (2b)

CONCLUSION: de-installing the seperate On my Windows7 system, the bundled EnergyPlus 8.2.0 (Windows 7) does not help ! The deeper causes remain unclear.

is useless, and in order to perform simulations I need an extra EP 8.2.0 installation.
