Lightroom Classic no inicia en mi pc

Please provide the actual version number of Lightroom you have installed on your system.

Tengo Windows10 versión 2016, no da incompatible con Lightroom de escritorio, por eso no sé porqué no puedo abrirlo. Sé que para LR nuve se necesita una versión de Wind más nueva pero para la de escritorio no me lo exige así que no sé que hacer-

GoldingD muchas gracias por tu respuesta. Eliminé LRDATA porque lo leí de un usuario registrado acá como mencioné anteriormente. Siempre cierro correctamente. 

Did Lightroom Classic close down properly the last time you used it, or did you force quit it, or worse, did it crash?

At any rate, in the folder your catalog is in, with Lightroom Classic not running, is their a lock file in existence? Use the Internet to search on "Lightroom Classic Lock File" to find and read an document on lick file, in your language.

And, why did you think deleting Previews.LRDATA was called for? Do you have a link to that? Deleting that is not disastrous,  but I cannot think of why. Deleating that file may affect any AI masinking you did, in that when you select a particular image with AI masking, the mask will get recomputed, slowing things down for a bit.
