Unfortunately, you need to reinstall if you want to use the LR5 stand-alone version.
Or, you update your subscription which will activate the Develop module in the current install.
Thanks for your prompt reply.
I have LR5 -(version 5.7.1 64 bit) currenly on my pc. I have found LR installation files (saves on having to download) with the following versions: Lightroom_5_LS11_win_5_3 through to Lightroom_5_LS11_win_5_6 witch one should I install(so it will not be consider LR CC)?
I actually would suggest the latest LR5 version which is 5.7.1
If you don't want to download, use the latest you have, 5.6 if the file 931MB in size, it should be the correct one.
Thanks again....will reinstall 5.6
