What to do, how to establish?

WHY You don’t have ANY answer, will be something to do with this problem or not?!

I resent that attitude!

Hi Igor,

Very sorry for the wait in reply, We have been working on the issue.

We always get back to our users. We have encountered this problem once before yet can not replicate on the 30 plus computers with the same spec as yours in our office. Do you have time to contact us today? we will actually log into your computer remotely and do our best to fix it. It would be great to know why 1 in 1000 computers does this and you could really help us. In return we will extend your license for free.

I am talking with the developer as I type and he is asking what the system language is set to ?System language.jpg
And what Language of Sketchup did you buy?

Kind regards


All questions - answers I will form 2/1/2015.

I thank for responsiveness.


Has made as you advised (the post above), on Item К which has Windows 8.1 PRO x64 (the version of OS Microsoft Windows 8.1 Professional v6.3.9600.17476, SketchUp 2015 PRO x64) with accessible various language packages, screenshots I apply;
- - - - - - - .

As a result of installation “PlusSpec” the same errors as well as those have turned out that were at Me, on my laptop with Windows 8.1 x64 (RU for one language) in we wash a post 1 in this theme

I am afflicted that I can not even to test this “PlusSpec”!

This problems is not only at me! Also other users on the Internet (I saw) have a similar problem with “PlusSpec”!

WHAT now further to do?!
Only do not speak to me that I should buy a new operating system in Australia, at me will be only these… That I have now!

The original of my message in case of bad transfer.

Сделал как Вы советовали (пост выше), на П.К. который имеет Windows 8.1 ПРО x64 (версия ОС Microsoft Windows 8.1 Professional with Media Center 6.3.9600.17476) с доступными различными языковыми пакетами, скриншоты прилагаю;

В результате установки “PlusSpec” получились такие же ошибки как и те что были у Меня, на моем ноутбуке с Windows 8.1 x64 (RU для одного языка) в моем пост 1 в этой теме

Я огорчен что не могу даже опробовать этот “PlusSpec”!

Эта проблемы есть не только у меня! Также у других пользователей в интернете (я видел) есть подобная проблема с “PlusSpec”!

ЧТО теперь дальше делать?!
Только не говорите мне что Я должен купить новую операционную систему в Австралии, у меня будет только эти … что я имею сейчас!


To me have answered:

Мне ответили:
Скачал, попробовал установить НО, результат отрицательный, опять ошибки:

Has downloaded, has tried to establish BUT, result negative, again errors:
