Hi guy. I am an architect. I would like to ask if its possible to use a sketchup 2019 license on a previos version? I am experiencing alot of bug using the latest version. I wish to use the sketchup 2018 stable version. ---

Only if you have one, each version of SketchUp has its own serial and autho code. When did you buy? ---

nope, license data is version specific. But you can ask your license source if downgrading is feasible. Before doing that investigating the issues you are experiencing would be a a more sensible behaviour, i.e. describing the problems you have for getting them fixed before downgrading is the common way. ---

Reporting bug is abit of a hassle for me. Lol. I am experiencing problem with material. I drag an image into sketchup, then explode the image to use in as texture. Usually sketchup will auto create a texture, but in 2019, it was missing from the material tab. I thought it was my renderer soft bug, but it seam it was 2019. Here is the model. I am not in front of my pc right now, but you can download the model from the thea render forum. [https://thearender.com/forum/viewtopic.php?f=171&t=25622](https://thearender.com/forum/viewtopic.php?f=171&t=25622) Do they still sell 2018 license? Is it possible to change my license? ---

There are other bugs, but i dont keep track of it. Usually i would just find a work around. I did not experience as many bug from previos version then 2019. My office just bought the 2019 license for ofis pc. I am used to the 2018 on my laptop. ---

If you don’t report bugs, then nobody knows about them and they don’t get fixed… The problem you outline hints at an incorrect installation for v2019… Incorrect installation affects drag-n-drop and also folder/file permissions - these affects are subtle and unpredictable… But it’s easy to address… Do the following… While logged in as your normal Windows user-account [NOT the separate system administrator - BUT having some admin-powers as a normal-user is OK] Ensure that SketchUp is closed. Find the v2019 SketchUp installer exe file - probably in your Downloads folder. Select the exe file’s icon, right-click \> context-menu \> “Run as administrator” When prompted choose “Repair” [obviously for a new installation it’s “Install”]. When it completes, restart SketchUp and test to see if things have improved. Installing a complex app like SketchUp in any other way will produce some weird results… So NEVER double-click the exe file or just ‘Run’ it - the resulting installation will be flaky - even if you have some admin-powers ! Another issue that messes with drag-n-drop [and other things] is the properties settings for the installed SketchUp.exe… Never have it Properties \> Compatibility set to “Run this program as an administrator” - that will stop Windows Explorer interacting directly with SketchUp, because their permissions will then differ, and be incompatible… Yet another issue often arises from copying Extensions between versions - it’s always best to reinstall these from scratch - Extensions’ versions can be updated to suit newer Ruby-versions, and sometimes critical folders of support files get missed in the copying-over process… ---
