Have you tried manually installing 4.5.2 .net framework?
Edit: I read your post too quickly...looks like you have tried the "standalone" installer....sorry I have no other solution
See SU help center:
C
Edit:#2
I had this same problem and I cannot recall the order of install but I believe you have to do the C++ runtime install as well (maybe before .net install?)
see paragraph #5 of this link
Riccardo,
Perhaps see this thread: (sdmitch was gracious to private message me a custom solution for my needs)
http://sketchucation.com/forums/viewtopic.php?f=323%26amp;t=57803
Perhaps sdmitch will see this thread, and allow or share the same plug-in for you, as I think this may be what you need to sort out your lmported model layers. (Maybe pm him?)

Voted yes.......never used SubD......Vertex Tools......or QuadFaceTools (seems req'd minimum).......so if this goes off I,m fairly certain whatever I manage to produce will be (if recognizable) an _ for effort. 
Best regards,
C
PS......I regularly follow/enjoy the SubD examples thread.......so I know already what some of you are capable of!
You did not mention how you are trying to print (export to .pdf/direct to printer) or the size of the sheet. (8.5x11?)
In either case you must make sure the tick box for size is set to actual. (Not fit to page)
And make sure the sheet size including any margins is large enough for full scale printing.
In your case 8.5"x11" is more than adequate for a 2"x4" rectangle.

+1 for video.........time lapsed please 
Awesome work btw.....& have been following/enjoying this thread.

Thank you Pilou! .....I did not fully understand your earlier scaling example (w/o visible dimension)....it is now very clear!
Now OP has at least two methods to adjust imported CAD files to scale.....as we understand his needs.
Best regards,
Charlie
PS.....RE: Try it....................I will now use this method as well!
I think without further input from OP Pilou we may just be guessing as to specific scaling required.
Found this video on YouTube to illustrate scaling as I understood OP request.
Tape Measure tool can also be used to set scale in Sketchup.
I use this often when importing CAD files.
Import CAD file........group if not grouped automatically......using tape measure tool measure a known distance (endpoint to endpoint)and enter known distance.....SU will ask you if you wish to resize the active group or component?........yes.
(If not endpoint to endpoint select ctrl to toggle guides off and do same as above)

Just a wild guess.......perhaps LO is trying to regenerate a (heavy/complex) model on said page......maybe you could temporarily unlink the model(s) specific to that page in your LO file.
If that allows access to that page (after unlink) than............bobs your uncle.

I could have given more detail in my original reply.
Orthoganally can certainly mean at "right angles" (of or involving right angles).
So obviously you could have objects at right angles of one another yet not aligned with LO vert./horiz. grid.
So locking shift while trying to copy/move off of non vert/horiz.....but at right angles(not aligned to grid) proves difficult.
Now I think I have accomplished an over explanation that may prove to confuse.
When copying and while ctrl is depressed....also press shift key. (to lock vert/horiz)
This doesn't work perfectly all the time, but does maintain a good degree of vert/horiz position.
Perhaps you mean a skewed angle when you say orthogonally?
C
You have overlapping faces which is the cause of the missing lines. (Z-fighting)
Also, you have geometry on layers other than zero, this will always cause problems in SU. (always has)
Better to keep all geometry on layer zero and put groups/components on layers other than zero to control visibility or in this case color by layer.

Hello slbaumgartner
I could not get Jim Foltz's script for this however much I Googled for it. I could not find it in his Web site's my plugins" too.
Any help would be greatly appreciated.
Thanks in advance

This may be the one TIG was referring to. (by Jim)
I have found that disable thumbnail on save results in faster saves, and in the past, resolved crashing with very large file.(thousands of component instances)
If you can live without the thumbnail as I can........Model info......file......(untick)redefine thumbnail on save.
This should at least allow you to turn autosave back on.

Was the wall you were attempting to select on the "cut" side if an inactive section cut?
Did you close sketch up and re-start and try to select same?

Note that when my viewports change over to referencing just one SU file, the SU file that is no longer being referenced by the viewports is actually no longer shown at all in the Document Setup dialogue box under the reference files list. The file is apparently being purged.
Just a wild guess......maybe it is a file path/file name glitch.
Are the two files identically named the same to a point?
I.E.:
johnsonresidencemodelofexistingconditions.skp
johnsonresidencemodelofnewconditions.skp
And stored in the same location?
Again, just guessing

Really odd, started happening yesterday.
I re-loaded drivers (the latest)... to no avail.
Happens in SU and LO, as well as other apps.Mac, El Capiton whatever is latest official release.
CAD Mouse misses clicks it seems, or jumps them together.Anyone else seeing this?
bmike,
How many "miles" on your mouse? (seriously)
I ask because it could be a weak "spring" within the mouse. (micro switch)
Is it limited to say the left mouse button or a "most used" button/switch?
I have "rebuilt" my MXrevolution left button (twice now) due to failure of a "spring" within the micro switch.
After it exhibited the equivalent as you describe. (missed click/doble click)
anyway....food for thought.
Charlie
If you are printing to .pdf with a print driver/Acrobat, why not just use Layout's export to .pdf?
Exporting to .pdf from Layout maintains sheet size.

You do not say if it is more than one texture applied.
However, you can go to in model materials,and delete the offending material. (rt. click delete)
You will then see a prompt to replace with default material.
Hope this works for you.
